IMPROVEMENT IN INSTRUMENT I'Olt DRAWING NAILS.

Be it known` that I, EDWARD P. WHITNEY, of Stamford, in the county ofFaireld, and State of Connectiout, have invented a new and improvedInstrument for Drawing Tacks, Nails, Spikes,`&c.; and Ido hereby declarethat the following is a full, clear, und exact description of the same,reference being had to the accompunying drawing, forming part of thisspecica-tion, inwhich- Figure 1 is a side elevation of the instrument,the lower part thereof being shown in section.

Figure 2 is a plan o r top view thereof.

Figure 3 is an inverted plan view ofthe shoe and claw part of theclaw-head.

My invention consists in the combination, with n. clawhead, of a footershoe, the former being pivotcd,o1 so connected to the latter, that therequisite depression of the lever or handle, to draw the tack, canbeeiected without the'heel ofthe claw-head resting upon the article intowhich the tack is driven, and hence the said articie is not marred bytheoperation of drawing the tack.

A designates the claw-head, provided with a bifurcated forward end, a,as usual with tack-drawers, and b is the shank or lever for operatingthe said claw-head, provided, in the present instance, with a handle, c,(see iig. l.) But the handle @may be dispensed with, and a tack-hammerconnected te the end ofthe shank instead thereof,'if desirable. y

B is a foot or shoe, to which the clawhead is pivoted. In the presentinstance the pivot passes through the side-walls ofthe shoe, andthrough. an eye in the claw-head, and holds the heel of theclaw-head-elevated in the shoe, the-pivot being thev fulcrum' for theclaw-head and shank. The bottom of the shoe has a smooth face, and itsforward'end has a piece removed, as shown in fig. 3, and the claw-headisi-so shaped that the face or lower side of the claw 'a projectsthrough this opening, and when the claw is in its normalcondition thesaid v lower face of the claw a is llush with the bottom of the shoe,thus placing the claw in a proper position to push it under the head ofthe tack, as will appear obvious by reference to igs. 1 and 3.

C is a ilat spring, having its upper end secured to the shank b, and itslewer'end curved, so as te bear upon the rear part of the shoe, theeffect of which is to keep the lower face of the claw thrown down Hushwith the bottom or lower face of the shoe. I will here remark that otherstyles of springs can be applied to effectl the saine end; for example,a spiral spring could be set in, so that its respective ends would bearagainst the shoe and the heel of the claw-head. And I will furtherremark that it is not absolutely essential that any spring he employed,asthe other parts would operate successfully without this feature.

I do not limit myself to the precise manner heroin shown, of pivotingthe claw-head in the shoe, nor to the exact construction herein shown.The object accomplished by my invention is to so combine the claw-headand shoe (with or without a spring) that in drawing tacks, the heel ofthe claw-head shall not bear upon' the article intoi'which the tack isdriven, and thereby greatly lessen the liability oi' marring sucharticle, which often occurs when tack-drawers of the ordinaryconstruction :irc used.

I have found this instrument especially adapted to drawing the tacks incarriage-tops, where there is great danger of scratching or marring theleather or other article with which the frame is covered, if an ordinarytack-drawer be employed, whose heel bears on the article and mars itwhen the handle is depressed `to draw the tack. With my invention, theflat face of the shoe rests. firmly on the article, and is not movedduring the drawing of the tacit. The bifurcuted end of the claw-headbeing iush on the under sidc with the bottom face of the shoe, enablesthe claw to be readily inserted under the head of the tack or nail.

What I claim as my invention, und desire to secure by Letters Patent,is- 'I v 1. The combination of the claw-head A and shoe B, constructedand operated substantially as and for the purpose herein specied. I

` 2. A spring, C, in combination with the claw-head A 'and shoe B,substantially as and for the purpose specified. l
